Multi Level Inheritance C++ HackerRank solution

Inheritance is one of the crucial steps to learning Object-oriented programming. The Multi Level Inheritance in c++ is one of four Inheritances, thus by solving the problem you’ll learn how inheritance can be used in code reusability. This tutorial will help you with Multi Level Inheritance C++ HackerRank solution.

Solution

We’ve created a base class named A which is later derived by a class named B. Later in the next step C is derived from class B creating a Multi Level inheritance. An object of the C class is created and print functions are executed respectively.

#include <iostream>
#include <algorithm>
using namespace std;
 
class A{
    public:
    void prnt(){
    cout << "I am a triangle";}
};
 
class B:public A{
    public:
    void prntB(){
        cout << "I am an isosceles triangle\n";
    }
};
 
class C: public B{
    public:
    void prntC(){
        cout<< "I am an equilateral triangle\n";
    }
};
 
int main() {
    C obj;
    obj.prntC();
    obj.prntB();
    obj.prnt();
 
    return 0;
}
